Persons post stroke executed stepping activities under four conditions: standard of care, interacting with: an off-the-shelf Microsoft-Kinect game, with a self-paced repeated custom video game and a game-paced random custom video game. Exercise intensity (neuromuscular and cardiovascular), enjoyment and perceived effort were measured during and after each condition.
Persons post stroke were first familiarized with the four exercise conditions and then instrumented with a metabolic system and heart rate sensor. They played the games in two counter balanced blocks: repeated (standard of care and self-paced repeated custom) and random (Microsoft-Kinect game and game-paced random custom). Games were played for 8.5 minutes with ten minutes of rest in between so they could return to physiological baseline. During exercise they reported exertion and at the end of teach exercise trial they completed an enjoyment questionnaire. At the end of the first block, participants removed the metabolic system's mask and were assessed for motor recovery. Performances were video taped. At the end of data collection preferences for the activities were ranked and participants answered open ended questions. Data for neuromuscular and cardiovascular intensity, enjoyment and perceived effort were reduced and analyzed using a Repeated Measures Analysis of Variance (RMANOVA) with the appropriate post-hoc corrections. Where possible clinically meaningful changes were calculated.

Participants performed stepping movements that were either cued by the investigator or interacted with a video game. There were three video game exercises that all involved stepping in either a repeated or a random pattern that was either self-paced or game paced.

Neuromuscular intensity
movement repetitions (stepping and marching) measured through video tape measured continuously during each exercise bout
Time frame: collected continuously during each of the four conditions. Collected in a single 2 hour session
Cardiovascular intensity (metabolic Units)
metabolic units measured continuously during each exercise bout
Time frame: collected continuously during each of the four conditions. Collected in a single 2 hour session
Cardiovascular intensity (Percent of maximum heart rate)
the percent of the maximum heart rate
Time frame: collected continuously during each of the four conditions. Collected in a single 2 hour session
Enjoyment
measured with the PACES questionnaire after each exercise bout
Time frame: four times collected in a single 2 hour session (once at the completion of each the four conditions).
Borg Rate if Perceived Exertion Scale
Measures perception of effort on a scale of 6-20
Time frame: Collected three times (at the beginning, middle and end) of each of the four exercise bouts during a single two hour session
Preference ranking
ranking exercise preference from highest (1) to lowest (4)
Time frame: collected once at the end of the completed data collection of a 2 hour session
Fugl Meyer Motor Assessment Scale_ Lower Extremity Section
measure of lower extremity motor recovery
